A phenomenon in this case at least as strong as the density effects is
the size sorting that comes from the details of packing. Google for

Thanks to both Bruce and John for pointing me to "Brazil Nuts." Not
the first search term I would have guessed...

Actually, the spheres are all 6mm in diameter (nominal -- I don't know
the variance), so size shouldn't be the predominating factor. The
particle-size sorting is pretty cool, though.
